We had a short meeting at 9:30 today on 19 March for the plan of next couple of days. Now setting up of the machine is going on. Ishi-san is a bit worried about the foil. It looks slightly bent. If necessary, he will change it later.

We decided not to measure linac emittance and momentum spread today. It will simply take long time. However, we may find some time during this experiment period, hopefully next week, for the measurement. Today's main measurement is the set up of BPM with difference signal from two electrodes and vertical coherent oscillation measurement.

Amplifiers are connected to up and down electrodes, but one of the signals does not come out. Ishi-san swaped the cables from the connectors of the chamber. Signals are also swapped meaning that the cables are OK. Ishi-san suspects there is a open connection between an electrode and cable. Ishi-san and Uesugi-san will open the chamber of vertical BPM now. This may take all of the rest time today.
